Core i7/X58 Overclocking Thread

[Pisklink]

I'm running 212 x 19 at this moment and wanted to add HT as well. However CPU-z reports only 2 cores are in use if I turn on HT in bios. Anyone a clue what the reason could be? I thought it was just turn on the HT setting in bios but maybe I'm forgetting something.

Additionally (but in a different session) I wanted to try turn on some energy saving option. But which one should I use so my comp. won't run 100% when idle all night? Or should it be disabled when OC'ing at 4Ghz?

How is this possible? Even at default settings with RAID enabled CPU-z still reports only two cores.

Yep, something not right here - does task manager report 4 cores or two?
- check bios make sure all four cores enabled, if yes, reset bios to load basic defaults see if that gets your four cores back.

Initially I thought it could have something to do with an energy saving setting and only 2 cores are active to save energy. So I disabled those settings in the bios and tried again but without any difference.

The weird thing is that when I use my OC profile all four cores are back but when enabling HT in combination with this OC profile it gets back to 2 cores again.

I will try the following things:
- Set default bios settings by using the reset button on mobo;
- Look how many cores CPU-z and task manager report with HT enabled and disabled at bios defaults;

In case CPU-z and task manager reports 2 cores with HT enabled and 4 cores with HT disabled, I could safely conclude that HT doesn't work correct? Is it possible to flash my bios again with the same bios version or should I revert to a lower bios version if possible?
